sNAPPiNcROLLSV Foie'ooRN'f'HARvEsTERs SPECIEIGATION forming partlof Ltterfsratent No. 799,438, dated May 26, 1903. Application tiled February-4,19Q3Mberial Ne. 141,899. (Ne model.)

Indiana, have invented new and usefulfImprovements in snapping-Rolls for Corn-H arvesters, of which the following is a specification.

My invention relates vto improvements in" snapping and conducting rollsV for corn-harvesters; and the object of the same is to .con-

'. struct improved rolls of this description whichsnap off the ears, carry them along and loosen the'husks thereon, and husk many of the; ears i before they pass over to the husking-rolls."

The simple and novel construction emv ployed by me in carrying out my invention is Vfully described and claimed in"this specification, and illustrated in the accompanying drawings, forming a part thereof, inwhichfl Figure 1 isa front elevation of a harvester equipped with my improvedrolls. Fig. 2is

a plan view of the rolls. Fig. 3 is a sectionv on the line 3 3, Fig. 2. Fig. 4 is a section on the line 4 4, Fig. 2. Fig. 5 is a section' on the line 5 5, Fig. 2.

Like numerals of reference designate like parts in the different views of the drawings.

The numerall designates the outside snapping-roll, and 2 the inner roll, which rollsextend substantially parallel throughout their lengths excepting their forward ends, which are beveled to form conical noses 3. Spindles 4 and are formed on the rolls and are jour-'.1

naled in boxes 6 and bearings 7. VThe boxes are supported by brackets 8, secured to side barst), which areconnected at their rear ends i by a cross-bar 10,within which the bearings 7 are located. The spindles 5 carry gears 5EL for driving the rolls. Spiral ilanges 11 are formed on the..roll 1 and extend throughout the length offthe nose.v 43 `aud about one-fourth 'of the lengthof the body portion ofthe roll. The roll l2 has spiral flanges 12thereon, inclined oppositely from the fianges 11 and extending throughout the length of the nose 3 thereon or a little beyond. Formed in the-roll 2, beyond the flange 12 and located to mesh with the flange 11, is a spiral groove 13. This construction enables the surface of the two rolls :1 and 2te be .brought'as close together as desired. The sections of the roll 2, subtended by'the-convolutions of the groove 13, are groovedlongitudinally to form ridges 14, w-hichlserve to engage and loosen the husks on the ears.Y The combination of ilanges 12 and grooves 13 extend throughout the length of thenose Sand about one-fourth the body of the roller, as does the liange 11 on the roll 1.

lThe-remaining three-fourths of the body is *grooved/longitudinally to form ridges 15, the

outerfaces offthe ridges on the opposite rolls b'eing located to oppose each other and come Yin contact when'the rolls are set suiiciently fclose.. The rolls 1 and 2 are set at an angle of fromthirty to forty-tive degrees and driven by 'suitable chains or belts connected to the masterfwheel of the harvester. I The stalks are iirst caught by picker-chains 'or other feeding means and brought opposite theY noses 3, between which they then pass as Ythe machine progresses and are caught by l`the spiral anges 11 and 12, which force the stalks downwardly and snap oft' the ears, which are then caught by the flanges 11, meshing with the grooves 13, and the husks thereon loosened, after which they pass to ythe opposed ridges 15, which -pull off the .greater portion of the husks before the ears pass on to the husking rolls, the work of which ismuch lightened.

l'dofnot wish to be limited as to details of vconstruction, as these may be modified in manyparticulars without departing from the .spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1i The combination of an outer 4snappingroll, having a cigar-shaped 'orco'nical nose, said roll having a 'spiral'flange thereon which extendsthroughout the length ofv the nose and-about one-'fourth'the lengthof the body thereof, the remaining portion of said roll being grooved longitudinallyto form ridges,

IOO

mentioned flange discontinuos and extends up to the end of the flange on said outside roll and meshes therewith, the remaining portion of the body of said inner roll being grooved longitudinally to form ridges which oppose the ridges on said outside roll, substantially as described.

2. In a snapping and husking mechanism, the combination of an outer roll having a tapering nose, said roll having a spiral flange thereon which extends throughout the length of the nose and a portion of the body thereof, the remaining portion of said body having longitudinally-extending ridges thereon, and an inner sn apping-roll mounted substantially parallel to said outer roll and having a tapering nose thereon, a spiral flange formed on said inner roll and a groove connecting with the end of said flange and meshing with the flange on said outer roll, said groove extending up to the end of said last-mentioned flange, the remaining portion 0E said inner roll beyond said groove having longitudinally-extending ridges thereon which are 0pposed to the said ridges on said outer roll, substantially as described.

3. The combination of an outer snappingroli, having a beveled nose thereon, said roll having a spiral flange thereon which extends throughout the length of said nose and a portion of the body of said roll, the remaining portion of said roll havinglongitudinally-extending ridges thereon, and aninner roll having a beveled nose and a spiral groove therein which meshes with said spiral flange on said outer roll, the portions of the roll intervening between the oonvolutions of said groove having ridges formed thereon, and the portion of the roll beyond said groove having ridges thereon opposed to the said ridges on said outer roll, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
